No Richard: Bunnahabhain compared their positions towards foxes (shooting ok) with the position towards birds (shooting not ok).
Necessity wasn`t mentioned. Neither was an alternative shown for hunting birds (using falcons etc. would be more like coursing, which is felt undesirable concerning foxes).

As to a moral approach one should consider that death by predator is natural for game - much more natural than the conditions chicken, pigs and cows living in on what are more meat-factories than farms.
Which exist because the general public (non-hunting) wants to buy the cheapest meat around ignoring that this causes inhuman conditions for animals.

Grab is quite right: game is more carefully (i.e. !ecologically correct") managed than most farm animals.
